A gas regulator is a device that controls the pressure of gas flowing from a storage tank or pipeline to a specific application, such as a stove or furnace. It ensures that the gas is delivered at a safe and consistent pressure, preventing damage to appliances and reducing the risk of leaks or explosions. Gas regulators are commonly used in residential and commercial settings, where they help maintain the proper functioning of appliances that rely on gas, such as water heaters, ovens, and heating systems. By regulating the pressure, these devices contribute to efficient energy use and safety in gas distribution systems.
